Getting Closer

The Kepler spacecraft may have found the most Earth-like world yet. Though not yet confirmed, the exoplanet orbits a star similar to the Sun within that star's habitable zone, which means it could support liquid water on the surface, and, therefore, possibly life.

The world, assuming it does exist as more than a mathematical glitch, is 1.5 times as large as Earth. Nailing down its existence, or non-existence, is clearly a priority.
